flit: firtzhntje refemt it in that: items emu mm making part at the same.

TO ALL WHOM I1 MAY GONOERN:

Be it knownthat I, DAVHIR. P. HIL'L, of Morgantown, in the county of *Mouongalia, and State of West Virginia,.have invented a new and improved Paint-Oil; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable others skilled in the art to make and use the same.

invention has for its object to furnish animproved paint-oil, prepared from petroleum-oil, for inside and outside painting, which will it? sooner thanotheroils and when (lg will make u fine gloss, will be harder, and more substantial, which shall have a splendid body, working easier and flowing more freely from'the brush than other oils.

And it consists in the paint-oilformed of the ingredients combined with each other in the proportions and manner hereinafter more fully described. v

In preparing this oil, I first pulve'rize twenty pounds of rosin and one-half pound of sugar of lead, and

mix with them one pound of sulphate of zinc; I then add ten gallons of petroleum-oil, and bring the mixture to v a boil; I then slalie one pound of lime, and mix with it one gallon of linseed-oil, and add the mixtureto the mirrture first prepared.

This causes all impurities to rise to the surface, so that they may be skimmed oh".

I then add two ounces of glue, boil rapidly for one hour, and add two ounces of concentrated lye and one quart of'turpentine. .r e r When cold, I add oiie half ounce of creosot'e andlthe preparation of the oil is completed.

It should be observed thatthe creosote is used for destroying the odor of the petroleum.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent- An improved paint-oil, prepared of the ingredients, in the proportions and manner substantially as herein described and set'forth. I

The above specification of my invention signed by me, this 25th day of July, 1868.

I DAVID It. P. HILL.
